New Revision: 414065
URL: https://svnweb.freebsd.org/changeset/ports/414065

Log:
  During the exp-run in bug 208158, it was found that dns/powerdns gives
  errors with libc++ 3.8.0:
  
  dnspacket.cc:645:6: error: call to 'abs' is ambiguous
    if(abs(trc->d_time - now) > trc->d_fudge) {
       ^~~
  
  This is because abs() is being called with unsigned arguments.  Import
  upstream commit f2d05dd to fix it.
